The perfect solution for these types of samples is cold or cryogenic grinding. This involves grinding aids such as liquid nitrogen (-196 °C) or dry ice (-78 °C) which embrittle the sample by cooling and make it break more easily. Another advantage is the preservation of volatile components of the sample.
